Can you preserve orange juice in any way? Not fresh squeezed, we don't get "good" oranges here in the Midwest. I've read oranges don't dehydrate well, but the peeling does, which I guess would be fine for cooking with, but is there a way to process something like juice concentrate? In my mind I'm thinking something along the lines of the frozen juice concentrate cans that are SO cheap to buy. Since it's acidic it should can well, but don't know if there's any nutritional reason to have it on the long-term shelf.
